Neighbors who don't call anyone else
“My furnace went out in the middle of the night. I called about 10 different companies and nobody was available except Serene Comfort. The person on the phone was kind and courteous even at 3 am — the furnace was fixed and I was back to bed in no time.”
“For 15 years I had different companies maintain my furnace and AC every spring and fall. After my first experience with Serene Comfort I stopped my usual routine — I haven't looked back since.”
“I needed service on a cold February night. Serene Comfort was the only company available within an hour. They truly are a 24 hour company.”
“Heating and cooling wasn't anything I thought I could understand, but their technician explained how the whole system worked after installing a new furnace and central air.”
“Clean and prompt service — and they didn't keep me waiting around all day.”
“They did a great job. I refer them to all my friends and family.”
A 2-minute checklist that might save you a service call
- Check the disconnect switchesBoth at the outdoor AC unit and inside by the furnace.
- Check your circuit breakersA tripped breaker is a common, easy fix.
- Look for a blocked filterA clogged filter can shut a system down.
- Confirm the thermostat settingsRight mode, right temperature, fresh batteries.

Make your system last longer
Replace your filter every 1–3 months
A clean filter keeps the AC coil above your furnace from clogging, keeps furnace sensors clean through the heating season, and — most importantly — keeps the air in your home cleaner and healthier.
Rinse your outdoor condenser
Gently washing the outdoor coil helps prevent breakdowns and lets your AC cool your home in less time — saving money on every electric bill.

Common questions
Are you really available 24 hours a day?
Yes. We take service calls 24 hours a day, 7 days a week — including nights, weekends and holidays — for furnaces, air conditioners and commercial refrigeration.
Do you charge for estimates on a new furnace or AC?
In-home estimates for a new furnace or air conditioner are always free. For repairs, a diagnostic fee applies and is discounted when you have us perform the repair.
Which brands do you work on?
All makes and models, including Carrier, Bryant, Lennox, Trane, York, American Standard, Goodman, Rheem, Ruud, Amana and more — plus Copeland and Tecumseh compressors on the refrigeration side.
Should I repair or replace my system?
A good rule of thumb: if a repair costs more than about a quarter of the price of a new system, or your equipment is aging and inefficient, replacement is usually the smarter investment. We'll give you honest options either way.
What areas do you serve?
Troy and communities throughout Oakland, Macomb and Wayne Counties — including Rochester Hills, Birmingham, Bloomfield Hills, Royal Oak, Sterling Heights, Southfield, Novi, Farmington Hills, Warren and Detroit. See the full list.
